How to Expose
- 1. How to make an Exposure The Trinity and Beyond
- 2. White Balance AWB-auto white balance Daylight Shade Cloudy Tungsten Flourescent Flash Custom
- 5. The Trinity-Aperture Controls how large the opening is that lets light through to the sensor Called f-stops Full stops 1,1.4, 1.8, 2.0, 2.8, 3.5, 4, 5.6, 8, 11, 16, 22,32 Controls depth if field The higher the number the smaller the aperture hole is The higher the number the more depth of field To change the aperture press the AV button while scrolling with the main dial
- 8. The Trinity-Shutter Speed Controls how long light passes through to the sensor Change shutter speed with main dial Can be anywhere from 1/4000 second to 1 second to minutes 1/500=one five hundredth of a second 1” = one second Anything under 1/60 will have motion blur from your hands shaking (called camera shake) Bulb setting-shutter stays open as long as you press the button
- 12. ISO Controls how sensitive your sensor is Runs in multiples 50, 100, 200, 400, 800, 1600, 3200 100-400 for bright light 400-800 for less light 1600 for very dark situations After 800 you begin to have lots of noise Your ISO will affect the choices of aperture and shutter speed available to you A higher ISO will allow you to use faster shutter speed
- 13. Add all three and you have an Exposure Now we have to combine all three to make our exposure Set your white balance Set your ISO Make choices about aperture and shutter and use your light meter to get the correct exposure
- 14. Light Meter Measures the light coming into the camera This measurement allows you to choose the correct aperture and shutter speed Press the shutter release half way down to get a light meter reading The goal is to get the blinking bar in the center of the light meter bar Choose a aperture or shutter speed that you want to start with and then then scroll with the other (aperture or shutter speed)until you have the bar in the middle
- 20. Summary of Making an Exposure Set your white balance Set your ISO Choose your shutter speed or aperture Use your light meter to get the corresponding shutter speed or aperture Take the photo and check your LCD to see if it is properly exposed
